Problems solved by technology

[0005] The brewing process is an important period for the formation of tobacco leaf quality. At this stage, there are few studies on improving the quality of tobacco leaves by chemical regulation before brewing. Most of them still use the method of temperature control and humidity control to improve quality.

Embodiment 1

[0014] Embodiment 1 The preparation of the upper six slices of Yunyan 87

[0015] Take 2g of salicylic acid, 6g of potassium citrate, 15g of chitosan and 0.5g of calcium ascorbate, and dissolve them in 1L of water to obtain conditioner A.

[0016] In a field of Yunyan 87 in a production area in Hubei Province, the growth is normal. The regulator A is sprayed in the evening before the first six maturation of the upper part. bake.

Embodiment 2

[0017] The preparation of the whole plant of Example 2 Eyan No. 1

[0018] Take 1 g of salicylic acid, 4 g of potassium citrate, 10 g of chitosan and 0.3 g of calcium ascorbate, and dissolve them in 1 L of water to obtain conditioner B.

[0019] The normal field of Eyan No. 1 in a production place in Hubei Province, the whole plant was harvested, soaked with conditioner B after tying the poles, and hung in the drying room for drying.

Embodiment 3

[0020] Embodiment 3 The modulation of the middle leaf of Yunyan 87

[0021] Take 0.5g of salicylic acid, 3g of potassium citrate, 5g of chitosan and 0.1g of calcium ascorbate, and dissolve them in 1L of water to obtain conditioner C.

[0022] In a normal growing field of Yunyan 87 in a certain production area in Hubei Province, the central leaf binding rods with the same quality were selected, put into the barn for curing, and the conditioner C was applied to the fan of the heating room, and the spray was attached to the surface of the tobacco leaves with the circulating air.

Abstract

The invention relates to a quality-improving and harm-reducing modifier for tobacco modulation and a use method thereof. The modifier contains salicylic acid with the concentration of 0.5-2 g / L, potassium citrate with the concentration of 3-6 g / L, chitosan with the concentration of 5-15 g / L and calcium ascorbate with the concentration of 0.1-0.5 g / L according to the mass concentration. By means ofthe modifier, the adversity oxidative stress in the modulation process can be relieved, nitrate is restrained from being converted into nitrite, the content of TSNAs in cured tobacco leaves is reduced, the enzymatic browning reaction intensity is restrained, meanwhile potassium ions in the tobacco leaves are compensated for, and the sucking quality and safety of the cured tobacco leaves are improved.

Description

technical field [0001] The invention belongs to the technical field of tobacco cultivation and preparation, and in particular relates to a quality-improving and harm-reducing regulator for tobacco leaf preparation and a use method thereof. Background technique [0002] Tobacco leaf conditioning is a "starvation metabolism" process in which live tobacco leaves are cut off from the supply of nutrients and water, which can be understood as a kind of "adversity physiology" to a certain extent. During the curing process of flue-cured tobacco or air-dried tobacco, as the starvation metabolism time of leaves increases, the activities of SOD, POD and CAT decrease, the function of defense enzyme system is lost, and the ability of cells to remove active oxygen decreases, resulting in a large accumulation of active oxygen in tobacco leaves , the membrane system is destroyed, the organelles disappear, and the cells gradually die. With the progress of the conditioning process, various s...
